A week of torment

The next week was full of torment for you. You woke up each day at around noon, horny as all hell. But of course there was no release. All you could do was to wait for Emily to come home from school, with Eric in tow. She always texted you when she was on her way, so that you could properly hide in your room. Then you had to sit in your room and listen to the sounds of your precious little sister getting fucked, eagerly waiting for when they were done, so you could get your reward. A taste of cum.

It was the highlight of your day. And it didn't take long before you found yourself eagerly on your knees in your room, waiting for your sweet sister to reward you for being her obedient servant. Just that one taste of cum was heaven to you. It made everything worth it. She beamed up the first time she saw you on your knees, and that day you were rewarded with two tastes of their cum.

Then it was the usual chores. Clean her messy sheets, cook her a meal. You looked up recipes online, wanting to surprise her, eagerly hoping to get rewarded for your diligent work. Then it was back to your room before your parents got home late at night. And you could never sleep. You laid in your bed, hornier than you had ever been before, desperate for release. You laid there until the small hours of the night, when you finally fell asleep, eager for the next day of rewards.

Then came the weekend, and your parents were home for most of it. It was torment. Eric couldn't come over to fuck Emily, which means you had no cum to taste. And Emily had to stay more secretive. But that didn't stop her from coming into your room late on Sunday evening, to tease you further.

"I'm thinking of letting Eric fuck my ass tomorrow." Your cock hardens as she says it. "That will be fun, won't it?"
"Have you done it before?" you ask. Emily looks at you with a teasing smile.
"Now why would I tell you that? That's none of your business pervert." She caresses your crotch over your sweatpants. Teasing you, like she always does lately. And she's gotten so good at it. "Now I should get out of here before Mom and Dad notices. See you tomorrow." She kisses your cheek and leaves, leaving you pent up in your tight plastic cage. It took you longer than usual to sleep that night, but you finally pass out late at night, excited for what tomorrow brings.

As Monday comes, you sit eagerly in your room after getting your sisters text. It doesn't take long before you hear the door open, and shortly after that, the usual moans from her room. She is verbal as usual.

"Yes Eric, fuck my ass, fuck my slutty asshole. I'm your tight little slut aren't I?"

You groan into your pillow, humping the air as usual, desperate for release. You haven't cum in days. It's probably a record for you. You imagine her boyfriend pushing his cock into her ass, as you wish that you were in his place. Then after a while you hear two large moans, and then it turns silent. You know that Emily's ass is full of his cum. You get on your knees on your bedroom floor, waiting for Emily to come into your room. You hear the front door open, and then close. Then after a few minutes she's there. Wearing another one of your T-shirts, her favorite clothing this past week, and you see her cum soaked panties once again cover her crotch.

"Good boy John. Did you like what you heard?" You nod obediently. "Are you excited for your reward?"
"Yes Em." you reply. She cocks her head, and looks at your sternly.
"Is that all you have to say. Yes Em? I expect more from you. Beg for it." If you weren't on your knees you would have lost your footing there and then. "Beg for your reward John."
Your head spins, you can't believe how lucky you are. You can't believe that your sister would be this much fun, how in line with your desires she is.
"Yes mistress" you say. Another one of your mistakes, talking without thinking. You just called your little sister your mistress.
"What did you just call me?" she asks.

You've really done it now, you think, worried that you pushed this entire thing too far. "I'm sorry Em.. I...". She interrupt you again. "Don't say sorry sweetie. I like it. Mistress huh? Mistress Emily." She smiles widely at you and looks you in the eye. "Now beg for your reward. Properly"
"Yes mistress!" you blurt out. "Can I please taste the cum thats inside you mistress. I've been wanting it all day!"

Emily laughs, and looks at you lovingly. "Of course you can my cute little toy." You feel your cock harden. It seems like she's delighted that you've kicked everything up a notch. She does what you have been waiting for, she puts a hand inside her panties, a part of your shared daily ritual, but this time, her hand doesn't stop at her pussy as it usually does, it goes further, as she pushes her fingers into her ass.

"There's so much of it leaking out of me. And you have been such a good boy. Now open wide!"

You open your mouth, eagerly lapping up her two fingers as she puts them into you. It doesn't taste as sweet as it usually does this time. Less of her juices, more of Erics. But you don't complain. You suck his juices up with delight, relishing the taste before you swallow. Then she pulls her fingers out, but it doesn't take long before they're back in your mouth again.

"I think you have deserved seconds today for being such a good boy."

You moan as you lick up her gift. More of her boyfriends lovely cum. You swallow it and look up at her weakly, and you see Emily's smiling at you proudly. Then it's back to your usual chores. Time to do her laundry. As you wait outside the bathroom door for her to remove her panties so you can toss them in the hamper, Emily calls out to you.

"You know it's been a week since this all started John. I think it's time for you to get some release."

Your cock swells in its cage.
